Bertrand Delacretaz updated SLING-4013:
---------------------------------------
Component/s: (was: Extensions)
Validation
> Allow validator to act on non-required properties
> -------------------------------------------------
>
> Key: SLING-4013
> URL: https://issues.apache.org/jira/browse/SLING-4013
> Project: Sling
> Issue Type: Improvement
> Components: Validation
> Reporter: Konrad Windszus
> Labels: validation
>
> Currently all properties which are bound to a validator are automatically
> mandatory
> (https://github.com/apache/sling/blob/trunk/contrib/validation/core/src/main/java/org/apache/sling/validation/impl/ValidationServiceImpl.java#L384),
> i.e. if the property is not set a validation error will occur.
> In some cases the property is not required but if it is there (and not empty)
> it should be valid according to the validator.
> I propose a new attribute {{propertyOptional}} with a boolean value below the
> properties node of a validation node. The default should be false (i.e.
> property is required)
